A bevelled gear m, constituting the-third element of the differential mechanism is rigidly mounted on shaft 22.

At the beginning of a machine operation a partial rotation is imparted to shaft 22, as also disclosed in the above mentioned patent. When this takes place, the two differential members I03 and I 04 move toward the foot of the depressed key in mesh with a pinion IIO (Figs. 1 an to one end of a drum II! rotatably but non-shiftably mounted between partitions I20.

A helical stepped groove I2l having I ten steps is cut in the circumferential surface of I groove III.

this drum. This stepped groove I 2| is' engaged by'a roller I24 mounted on an extension I22 of a sleeve I20 slidably mounted on the shaft 10. On its other end, the sleeve I20 carries a plate I26 which embraces the shaft I2, Figure l, and thereby prevents the sleeve I20 from rotating about shaft 10. The plate I20 has open slots I21, I20 ngaging annular grooves I20, III, Figure 3. provided, respectively, on the right-hand end of the rider axle 0I and on the locking bar 00. By this engagement, these two members 0| and 00 take part in the lateral shifting motion of sleeve I23 caused by rotationof the drum IIO. When no key I02 has been depressed for an operation of the machine, the rider axle 0]. is adjusted into the position illustrated in Figure 4,,in which the riders 00 are out of mesh with the totalizer wheels 00, the appurtenant roller I24 engaging the first step from the right, Figure 3, of the stepped The other nine positions of the rider axle correspond to the nine keys of the appurtenant bank of keys I02. a shifting of the rider axle 0| from its old position immediately intothe new one takes place without an intermediate return to the idle position. The provision of a special idle position of the rider axle enables the use of a single diiferential member (wheel 19) for engaging the total izers, so that although all four rows of totalizers are engaged at once by this member, the value introduced by the diflerential wheel 38 (Fig. 1) need not be entered on a totalizer in every row, inasmuch as the rider on the non-selected totalizer will not transmit its motion to any of the counting wheels 00 upon the differential wheel being rotated by the main differential wheel 08.

For "addition" operations it is possible to shift the selected totaliser intoalignment during the operation, since the selected totalizers are not engaged until after the forward stroke of the diflerentials is completed.

However, for total" and sub-total" operations, the totalizer involved must be engaged bethe differentials begin their forward movement, which makes it necessary to either run the machine through a preliminary operation to se- It is apparent-that lect .the totalizer, for this p rpose. The present invention does not resort to this preliminary operation, but provides a simple means for selecting the desired totalizer by hand before the operation is started. This mechanism will now be explained.

,An adjusting lever I42 (Figs. 1, 3 and 8) having a handle I4I,is pivoted on shaft II beside each row of keys I02, which levers are resiliently held in their positions of rest illustrated in Figures 1 and 8 by spring pressed pawls I40, that engage notches I44 on levers'I42. Each lever carries a series of teeth I45 intended to co-operate with a pinion I" mounted on a shaft I40. The pinion I" is permanently in mesh with a series of teeth I40 on the above-described toothed wheel III, which is rigidly connected to the disk IIO (Fig. 3) and is connected with the drum H0 that produces the lateral shift of its rider axle or to provide other mechanism beside the uppermost key in, then the first tctalizer from the right (Fig. 4) is selected. When it stands beside the second key from the top, the

second totalizer from the right is selected, andso on. A, series-of locking teeth I40 (Figs. 1 and -8), cooperating with pawl I40, resiliently holds the lever in in its adjusted position. In this manner the totalizers are selected by the adjustment of the levers I 42 preparatory to a machine operation. Since the keys I02 are not used in taking totals, a special detent means (not shown) is provided to prevent them from being depressed during these operations. The keys I02 do, however, serve as a guide for the adjustment for the levels I42. 1 i

During a total-taking operation the differential members I 02 and I04 exercise no control over the selection of the totalizers, although they are actuated in the usual manner by the shaft 22.

During these operations the members I03 and I04 move so as to embrace the pin H2 in whatever position it is left after adjustment of the lever I 42.

The first tooth III of the series of teeth I40 -(Figs. 1 and 8) is somewhat shorter than the remaining ones to insure a smooth meshing with the pinion I4I. It is obvious that a correct selection of a totalizer by the lever I42 requires that the disk Ill be in its uppermost or home position, illustrated in Figure 1, before the lever is moved to engage the teeth I40 with thepinion I41. To accomplish this, the machine is given an idle operation with no keys I02 depressed, which returns the disks IIO home from whatever positions they assumed at the end of the preceding operation. I

It is necessary, however,. to perform such an idle operation only prior -to the first of a series of successive totaling operations, since the disks H0 and pinions I4I remain in correct alignment with the teeth I45 until the keys I02 are again used to select a totaliser for an adding operation.

This form of mechanism has the advantage of requiring only one machine cycle to perform a totaling operation, and needs an idle operation only in connection with the first of a series of such operations, which are manually performed at the close of a business day.

iii

The disk H8 is in connection with an appropriate indicator wheel (not shown) through the wheel 3, pinion I41, and a pinion I52 rigidly secured thereto, and with the corresponding type I wheel by a series of helical teeth I58 on the lower edge of the disk I I8 meshing with a helical gear I53 secured to a shaft I54. The positioning of the indicator and type wheels isobviously effected, like the selection of the totalizers, during the operation of the machine in adding operations,

and by a preliminary setting of adjusting levers I42 in total-taking operations.

The rocking motion of the shaft 12 to engage the selected totalizers will now be described.

Each shaft-12 has pinned thereto, on its left' hand end (Fig. 3), an arm 16 which carries two rollers 16 on one end thereof, engagingan eccentric disk 11. (Fig. 1) secured to the appurtenant shaft 14-. Each shaft 14 has mounted on it a pinion 18 (Figs. 1, 2 and 3), all these pinions 18 being permanently in mesh with a wheel 19 (Fig. 2) rotatably and shiftably mounted on shaft 22 together with a sleeve 8| rigidly connected thereto (Figs. 2a; and 8). The sleeve 8| acts as a mounting member on which is fixed an eight tooth pinion 82 and a four tooth pinion 83. The latter is formed from an eight tooth pinion by cutting out each second tooth thereof. Three a stepped groove 96 of a. segment 91 rotatably but non-shiftably mounted on shaft II. The segment 91 is further rigidly connected with a manipulative lever 98 by which it may be moved to different angular positions that correspond to the operations of adding and the taking of totals and sub-totals. Upon lever 98 being adjusted, the sleeve 8| is shifted by the stepped groove 96, and the pinions 83 and 82 are set on two corresponding disks of sets 84 to 86 and 81 to 89. The pinion 18 is of such a width, that it remains in mesh with the spur wheel 19 in spite of sleeve 8| being shifted. The disks 84, 85 and 86 each have surfaces concentric with their axis adapted to enter any one of the inter-tooth gaps of pinion 83, whereby the latter and the sleeve 8i, wheel 19 and pinion 82 are secured against rotation. As the diameter of Wheel 19 is twice that of pinion 18,the eccentric disks 11 are turned degrees on. each partial rotation of sleeve 8i. There are two such partial rotations during each operation of the machine, because each of the disks 81 toi89 has four teeth. Hence one complete revolution of the main shaft H in a clockwise direction (Figs. 2 and 2a), with the disks 84 to 89, causes one complete reciprocation of the arms 15 and thereby the engagement and disengagement of the totalizers with the intermediate wheels 36.

As stated above during each machine operation the differential wheel 38 at thecommen'ce- This is the conventional operation inmachines of this type. When an addition operation is to be performed, it is necessary that the totalizers the return movement of the differential wheels 38, whereby an amount corresponding to that set up in said differential wheels during their forward movement is transmitted to the totalizers. When a. sub-total operation is to be performed it is necessary that the totalizer be in engagement withthe pinions 36 during both the forward and backward motion of the differential wheels 38 whereby the amount taken from the totalizer wheels and set up on-the differential wheels '38 during their forward movement will be replaced onthe 'totalizer wheels during the return movement. Thus the taking of a sub-total does not affect the final position of the totalizers.

When a totalizing operation is to be performed it is .be in engagement with the pinions 36 only during necessary that the totallzer be in engagement with the pinions 36 only during the forward movement of the differential wheels 38, so that thelatter can rotate the totalizer wheels to zero and leave them in this position.

The time of engagement of the totalizers is controlled by the mechanism associated with lever 98.

The instant at which this engagement and disengagement takes place differs according to which of the recesses 99 and teeth l8! are in operative position.

When the hand lever 98 is set on Addition", the pinions 82 and 83 co-operate with the disks '89 and 86.

In this case the teeth. lllia actuate pinion 82 to throw in the selected totalizers during the return movement of the differential wheels 38.

After 'said return movement is completed the teeth |8ib actuate pinion 82 to throw the totalizers out. Of course at the same time, the recesses 99a and 99b release the pinion 83, whereby the above movements can take place. When the hand lever 98 has been set to the Sub-total positionj the pinions 83 and 82 are opposite the disks 85 and 88. I

In this-case the teeth l8lc actuate the pinion 82 to cause the selected totalizer to be engaged during both the forward and backwardmotion of the differential wheels 38. The teeth I Old are placed so asto actuate the pinion 82 near the end of the travel of disk 88 so that the totalizer'is not thrown out until the differential wheels 38 have completed their return movement.

82 to cause the selected totalizer to be engaged during the forward motion of the differential wheels 38. Upon completion of the said forward motion the teeth Nile actuate the pinion 82 to disengage the totalizer for the return motion of the differential wheels 38.

In the position of rest of the machine the pinion 82 is completely free from the teeth ml and pinion 83 is opposite an unbroken portion of the circumference of one of the disks 84 to 86,-so that, the sleeve 8! is free to be shifted without interference from the several gears and disks.

A fourth position of hand lever 98 and sleeve 8| may be provided as shown in Figure '7. in

which position the pinion 83 co operates with a locking disk 288 that has no recesses 99, and in which .the pinion 82 is not in line with a toothed disk. In this case the totalizers would not be engaged at all during the operatic-n of the machine, as is desired when an amount is to be printed and not added.

In the actual use of machines of this nature,

the simultaneous selection of a totalizer in each tion, to save the superfluous rocking motion.

A modified construction to perform this func tion is illustrated in Figures. 4a to 6. In this embodiment the shaft 12 associated with each row of totalizers is connected with the arm 15,

rocked by the eccentric disk 11, by a disengageable clutch. This clutch causes a coupling of the arm 13 with the shaft 12 only if a totalizer in that particular row is selected for operation. This mechanism will now he described in detail.

The arm 13 loosely mounted on shaft 12 carries a bolt I33, Figure 4a, displaceable in a sleeve I32, and. held in lateral position by a prolongation I33 of the extension l22 and; by two collars I33 secured to bolt I33. The prolongation I33 embraces the .bolt I33 by means of an open slot I33, Figure 6, that enables the bolt I33 to rock about shaft 12.

v When the sleeve I23 (Fig. 5) is shifted by the roller I23, the plate I23 that engages the rider axle 3| and locking bar 33, and the bolt I33 are shifted correspondingly, causingthe' bolt I ,33 to.

. enter a bore I31 (Fig. 4a) in an arm I38 rigidly mounted on shaft 12. This causes the shaft 12 to be coupled with arm "13 so that whatever totalizer is selected by a shifting of .the rider axle 3| will be connected with the actuating gears by a rocking of the totalizer frame when the eccentric 11 oscillates arm 13. It is obvious that unless a totalizer in this particular row is selected for operation, the'arm 1i and shaft 12 will not be connected and the ensuing movement of the arm will not have the effect of connecting the totalizer for actuation. It is also obvious that when the plate I23 and extension I22 are 'returned to the position shown in Figure 4a, the bolt I33 will return to its position shown, where it does not connect arm .13 to shaft 12.

In order to prevent the totalizer assembly from being accidentally engaged, a bolt I39 is fixed on the plate I23 in alignment with bolt I33, which bolt I33 follows the bolt I33 into bore I31 of arm I33, as the bolt I33 leaves it. In this mann'er arm I33 and shaft 12, with which the totalizer frame 33 is rigidly connected, are rigidly connected with plate I23 which has no oscillating movement at any time.

While the form of m herein shown and described is'admirahly adapted to fulfill the pbjccts primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims whichfollow.
